Page not showing

Hi – great plugin running it for a competition at the moment currently have 580 images on the site.

Please see at http://voting.irelandbabyshow.com/voting-gallery/nggallery/page/9/

It should go up to 10 pages though for some reason the plugin won’t let me go past 9. I have hit some kind of limit on the images i think – is this the case?

I tried increasing the number of images per page but all this done was reduced the page numbers.

I also tried manually typing in:

Please see at http://voting.irelandbabyshow.com/voting-gallery/nggallery/page/10

and strangely the page was there – its just not shown in the nav.

Any ideas?
